||Toxicology and hazard evaluation of cyanide fumigation powders
||1988, Vol.26, No.5/6, p.325-335. Illus. 8 ref.
||The typical fumigant powder is a mixture of 40% sodium cyanide (NaCN) and 60% kaolin. The acute oral toxicity of the mixture is proportional to its NaCN content; kaolin does not modify the toxicity of the NaCN. Release of hydrogen cyanide (HCN) gas from wetted powder gave potentially lethal concentrations of HCN at an application rate of 5g/m3, which is 5 times the recommended rate. The concentration produced by 1g/m3 was significant but not lethal. Application of fumigant powder to the eyes of rabbits produced conjunctivities and keratitis, and was ultimately lethal. Lethal amounts of cyanide were absorbed by abraded skin and moist intact skin, but not by dry intact skin. Thus, protective clothing and equipment should always be worn when cyanide fumigant powders are handled.
